摘要
针对GIS数据采集中属性信息采用手工调查和数据处理工作复杂等导致效率低下的问题,提出了基于AUTO CAD数字化采集GIS数据的方法。研究了将实体的属性信息编码进行数字化调查的方法,解决了GIS数据在AUTO CAD图形数据库中存储的问题,以及将AUTO CAD下的GIS数据转入GIS的问题,将大大提高了GIS数据采集的工作效率。
The efficiency of GIS data surveying is very low because attribute information of entity is surveyed by hand,and data manipulation is very complicated,so digital surveying way of GIS data based AUTO CAD is proposed in this paper.The method of coding attribute information of entity to realize digital survey is studied.As a result,the problem of storing GIS data in AUTO CAD graph data bank and transforming GIS data in AUTO CAD into GIS is resolved.Thus the efficiency of GIS data surveying will be improved greatly.
